Dear Friend

In this video you can see that how the tower crane moving by wind pressure, also you can see that there is no adequate supports provided at interval of floors / height of cranes.

All towers cranes are designed / need to be check on basis of IS 875 - Part 3 according to their wind zones, which is mandatory to required and provide apt support to towers crane

Its responsibility of all engineers regular check their supports if height of crane increasing along with floors.

Thanks
